Peptide libraries help researchers map epitopes, optimize binders and screen sequence space. We prepare overlapping peptide sets, alanine scans and custom positional libraries.
Library format, purity and plating can be adapted to ELISA, microarray or mass spectrometry workflows.
A library is a designed set, not a random combinatorial explosion. You specify the parent sequence, the window length, the offset, and whether each member is purified or crude. Crude overlapping peptides are common for first-pass ELISA mapping; purified members are used when a hit will be published as a single sequence.
Positional scanning and alanine scans answer different questions. Say which experiment you will run so that we do not synthesize more peptides than the plate plan can use.
